PAPER-B'OX-,COVERING MACHINE.

SEECIFJLCATION forming part of Letters Patent No. 731,140, dated June 16, 1903.

Application filed August 23, 1902. Serial No. 120,847. (No model.)

To @ZZ whom it may concern:

Be it known that I', ROBERT ANDREW THOMPSON, a citizen of the United States, re

siding at Martinsburg, in the county of Berkeley and State of Vest Virginia, have invented a new and .useful Paper-BoX-Covering Machine, of which the following is a specifica'- tion.

This invention relates to pape1boxcovering machines, and is designed to provide for guidinga plurality of strips of paper or other material for covering the sides of'a boX or lid,

and in particular to guide a pair of ornamental edge strips so as to have the latter underlie the respective longitudinal edges of the main strip in order that the three strips may be applied simultaneously to the box or lid. It is furthermore designed to have the guide adjustable, so as to accommodate any width of main strip, and to have theguides for the ornamental edge strips simultaneously adjustable with the guides of the main strip in order that the edge strips may always bear the proper relation with respect to the main guide. y y y Another object of the invention is to embody the same in the form of an attachment whichv may be conveniently applied to theV common or ordinary type of paper-boX-covering machines without alternating'or chang.- ing the latter in any manner whatsoever and withoutinterferingwith the operation thereof.

With these and other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown inthe accompanying d rawings,and particularly pointed out in the appended claims, it being nnderstood that changes in the form, proporjtion, size, and minor details maybe made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a side elevation of a common or. ordinary type of boxcovering machine having the present form of guide applied thereto. Fig. 2 is an enlarged detail plan view of a portion ofthe machine, showing the guide fitted thereto. Fig. 3 isa cross-sectional view on the line 3 3 of Fig. 2.

Like characters of reference designate corresponding parts in all of the figures of the drawings. v

To adequately set forth the application and operation of the invention, there has been shown in the accompanying drawings the supporting-frame 1 of an ordinary paper-boxcovering machine, having `the opposite terminal posts or standards 2 rising therefrom for the support of the substantiallyhorizontal and parallel longitudinal bars 3, which carry the opposite rollers 4 and 5 for snpporting the strips as they pass through the At the rear of the machine there per-rolls and a glue-pot or-paste-box 7. At the front of the machine are the strip-cutting apparatus S and arotatable box-'holder 9. It will be understood that these parts of the machine are common and well known and form no part ofthe present invention.

The'device of the present invention, which is. to be supported upon the longitudinal bars 3 substantially midway between the .ends thereof, embodies a substantially rectangular frame made up of longitudinal side bars 10 and end bars 1l and 12,1'espeotively. At the front of the frame are three transversely-disposed rollers 13, 14, and 15, which are journaled in the opposite sides of the frame and are disposed in the plane thereof. At the rear of the frame thereis a transverse roller 16, disposed in the plane of the sides, and another roller 17, located in front of the roller 16 and hung below the frame. Immediately in rear ofthe roller and below the frame is a standard 1S, having a longitudinal slot 19 and provided at its upper end with a fork or yoke 20, the opposite end portions of which embrace the vframe and are connected thereto by means of suitable fastenings 21, there bef roo bars 3.

ing a boss or shoulder 22 upon theinner side of each member of the fork or yoke and disposed to lie against the under side of the frame, so as to rigidly support the latter upon theyoke.

For su pporting the frame ofthe guide upon the. longitudinal bars 3 of the machine there is abracket consisting of asubstantially horizontal bar 23, which is provided with an intermediate longitudinal slot 24 and aterminal longitudinal slot 25. The standard 18 is applied transversely across the slot 24 and-is connected to the bracket by means of a bolt and thumb-nut 26, the bolt being projected through the intersecting parts of the slots 19 and 24, whereby the standard may be adjusted vertically and transversely. At one end of the bar 23 there is an upstandiug hangerarm 27, which is provided at its upper end with an inverted substantially U -shaped hook or seat 28, which is adapted to embrace the adjacent bar 3 of the machine, so as to support the bracket transversely beneath the There is a bolt 30, which pierces the arm 27 and the extremity of the hook or seat, so as to lie beneath the rod 3 and preventaceidental upward displacement of the hangerarm. At the opposite end of the bar 23 there is a duplicate hanger-arm 27, which is adjustable longitudinally of the bar by means of a bolt 3l, piercing the lower end of the arm and working in the terminal slot 25, whereby the bracket may be accommodated to machines of different widths.

The means for guiding the paper strips is located between the rollers 15 and 17 andernn bodies a pair of spaced cross-bars 32, rigidly secured tothe sides of the frame and forming ways for the opposite duplicate guide members 33. Each of these members consists of a rectangular body having a central screwthreaded opening 34. From the top of the body rises a substantially triangular ear or projection 35, which is flush with the inner end or face ofthe body and projects in front and rear thereof. From one end of the ear 35 there extends an integral lateral projection 36, which projects in front of the inner end of the body, and from the outer end of the projection 36 depends another projection 37, thereby forming an inverted substantially L-shaped guide projection at one end of the upstanding ear 35. At the outer end ofthe body is a pendent subslantially triangular projection 38, which is Hush withthe end of the body and tapers downwardly. As best indicated in Fig. 7, it will be seen that the body of the guide has a working lit between the crossbars 32, and the opposite projected` ends of the upright ear 35 slide upon the upper edges of the cross-bars, so as to support the guide in position. Moreoverythe pendent projection at the inner end of the guide is spaced at one side thereof, so as to lie at the-outer side of the adjacent cross-bar. It will of course be understood that the two guide members are revcrsely arrangedthat is to say,

the guide vprojection 37 of one member lies in front of the cross-bars 32, while the pendent projection of the other member lies in rear of the cross-bars. To simultaneously slide the guide members toward and away from each other, there is a screw-threaded shaft 39, which passes through the screwthreaded openings 34 of the guides and has its opposite ends journaled in the side members 10 of the frame. One end of the shaft is projected beyond the frame and provided with a suitable crank-handle 40. It will of course be understood that one half of the shaft is screw-threaded in one direction and the other half in the opposite direction, so that by turning the shaft the guide members will be simultaneously fed or adjusted toward and away from each other.

In explanation of the operation of the device it willbe noted that the guide is supported upon the longitudinal bars 3 of the frame of the machine and disposed between the glue-pot and the rotatable box-holder, preferably between the gnidesl: and-5, which are located between the glue-pot and the cutting apparatus. The main wide strip of paper A to cover the side of the box or lid passes from the glue-pot over the top of the roller 16, then between the ears 35 and over the cross-bars 32, alternately over and under the series of rollers 15, 14, and 13, thence through the cutting apparatus,and finally to the edge of the box or lid upon the box-holder 9. The ornamental edge strips have been indicated by the reference characters B and C, and each of these strips passes from the glue-pot, under the rollers 16 and 17, thence between the pendent guide projections 37 and 38 of the respective guide members, and below the cross-bars 32, thence over and under the series of rollers 15, 14, and 13, thence through the cutting apparatus 8, and finally to the box or lid. After the strips of paper have thus been fitted in place the crank-handle 40 is operated to draw the guide members toward each other until the central wide strip A has a working fit between the guide members. Simultaneously with this adjustment of the guide members the edge strips B and C are drawn inwardly with the members, so as to underlie the respective longitudinal edges of the main strip. It will now be understood that the under face of the main central strip will adhere to the edge strips and the three strips will be fed as a single strip from the guide to the box in a very simple and effective manner without interfering with the operation of the machine in any manner whatsoever or requiring any change of the reels, glue-pot, cutting apparatus, and box-holder. Prior to passing through the guide the edge strips are disposed below, and thereby separated from the main strip A by the upper and lower rollers 16 and 17, and in passing through `the guide the main strip passes over the top of the cross-bars 32 and the edge strips below the same and finally IOO IIO

IZO

come into contact, when they pass over the roller 15. Besides pressing the main strip into contact with the edge strips the rollers 13, 14, and 15 form a tension device to prevent looseness of the strips, and thereby insure a proper feed thereof.

As best illustrated in Fig. 5, it will be seen that it requires both of the guide members to form a guide for the main strip A, and by this arrangement the guide members may be moved toward and away from each other to accommodate the device to strips of different widths. As the ornamental edge strips are commonly of the same width, the guide for each strip is carried by the corresponding guide member-that is to say, the spaced pendent projections 37 and 38 of each guide member form a guide for one of the edge strips. -Hence the latter is carried with the guide member in its adjustment, and thereby always underlies the main strip for a predetermined distance. To accomplish this f eature, it will be observed that the upstanding ear 35 is disposed intermediate of the pendent projections 37 and 38, and hence the main strip always overlaps the edge strips.

From the foregoing description it is apparent that the device of the present invention is in the nature of an attachment for application to and removal from any ordinary form of paper-box-covering machine and is designed to effect a proper overlapping of the main strip of paper upon the ornamental edge strips, so as to have the three strips pasted together before they reach the cutting apparatus, whereby they are cut and applied to the box or lid as a single strip. Moreover, the attachment can be applied to the machine without interfering with any of the parts thereof, as it is supported upon the machine at a point between the front and rear supports for the strips of paper as they pass from the glue-pot to the cutting apparatus.
